Wife and I caught while giving bj. Both 30

We live in a small 2 bedroom apartment. With our daughter we had when we were 16. ( do the math). She was out with her bf and me and wife were in the living watching some tv. Time pass and we started making out and enjoying ourselves. She started getting on her knees and start to suck my cock she was going to town with me. I'm guessing we had the tv slightly to loud that we didn't hear my daughter unlocking the front door and opening the door. As soon as we heard the door open wife jumped up and I just covered up with a blanket we had near. Her bf walked in first then her and we were shocked and don't know if they notice what happen. They both went to my daughter's room and me and my wife went to our room to finish up the job. Great night of being risky a bit.
